Description

  The present invention relates to a disk loading system for an optical disk, and more specifically to a tray moving speed control method and a tray moving speed control apparatus.

  The disc loading system is also called a tray loading system.

  FIG. 1 is a schematic block diagram of a tray loading system according to the prior art. Referring to FIG. 1, the overall system for tray loading includes a front end and a back end, and the front end includes a tray motor 110, a servo controller 120, and a host interface 130.

  The tray motor 110 is a motor that drives the tray. The servo control unit 120 controls the tray motor 110 to be driven at a predetermined speed. The host interface 130 is connected to the servo control unit 120 and a personal computer or an A / A. It mediates information transmission between V (audio / video) 140. The back end includes a personal computer or an A / V player 140 and receives a user command from a user interface (hereinafter referred to as UI) or the like and transmits it to the host interface 130.

  Such a conventional disk loading system for optical disks loads / ejects (or opens / closes) a disk at a speed determined by a product manufacturer. That is, the optical disk loading systems currently on the market load / eject the disk at a speed determined by the product manufacturer. There is no way for the user to vary this speed, and from the standpoint of the product manufacturer, there is no separate command set that embodies this. Standards for host interfaces (ATAPI (AT Attachment Packet Interface), SCSI (Small Computer System Interface), ATA, etc.) that mediate data between the front end and the back end are defined for tray loading / eject commands. However, the contents regarding the tray speed are not defined. In addition, the tray controller opens and closes the disc tray according to a predetermined constant or table.

  However, the loading speed set by the product manufacturer at the time of product shipment cannot satisfy the tastes and sensibilities of all user groups, and is an important point in product selection. It is a fact that is reflected in the quality evaluation. In order to solve this problem, it is difficult for manufacturers to differentiate and sell disc loading speeds for one model. Recently, due to the trend toward slimming personal computers, the personal computers have become thinner and the vertical installation of optical discs has become frequent, causing the phenomenon that the discs get caught in the tray and the phenomenon that the discs are dropped when the tray is opened. Due to poor loading, the recording / reproducing performance of the disc can be degraded. Therefore, in some cases, it is necessary to vary the drive speed for opening and closing the tray for the stability of the optical disk drive.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a tray moving speed control method and apparatus that allow a user to adjust a predetermined loading speed.

  One feature of the present invention for solving the above problems is that in a method of controlling a tray moving speed, a) receiving tray moving speed setting information via a UI, and b) moving the tray from the UI. Receiving speed setting information via a host interface; and c) setting a tray moving speed according to the received tray moving speed setting information.

  The step a) includes a step of receiving setting information for testing the tray moving speed, a step of receiving setting information for returning the tray moving speed to a factory shipping speed, or the tray loading speed and tray ejecting. It is preferable to include at least one of the steps of receiving setting information for separately setting the speed.

  The step b) preferably includes a step of defining a command for speed setting in a standardized host interface and assigning a parameter for transmitting the speed setting value in the defined command.

  The step c) includes a step of searching for a moving speed value according to the received tray moving speed setting information from a speed table having one or more moving speed values, and setting the moving speed value to the tray moving speed. It is preferable.

  According to another aspect of the present invention, in the tray movement speed control device, a host interface that receives setting information of the tray movement speed input via the UI, and the tray movement speed setting information received from the host interface. And a tray controller for setting the tray moving speed according to the setting information of the tray moving speed.

  According to the present invention, by allowing the user to adjust the loading speed determined at the time of product shipment, the taste and sensitivity of each user group can be satisfied, and the recording / reproducing performance of the disc can be reduced due to poor disc loading. Decline can be prevented.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  In order to effectively solve the problems of the prior art, the present invention provides a dedicated UI for setting the speed for each step in a personal computer or A / V player on the back end side of the optical disc. The tray loading / ejecting speed input by the user is transmitted to the tray controller via the host interface to complete the speed setting. The present invention corresponds to any apparatus that includes an optical disc and performs a loading / ejecting operation by moving a tray motor.

  FIG. 2 is a block diagram of a tray loading system according to the present invention. Referring to FIG. 2, the host 220 includes a UI 221, and the UI 221 particularly includes a tray speed setting unit 222 for inputting tray moving speed setting information from a user according to the present invention. For such tray speed setting, a dedicated menu for inputting the speed can be provided.

  When a personal computer is used as a host, drive registration information or a separate input UI is provided, and the tray loading speed is input via this. As the speed input for each tray step, loading and ejection are input separately. FIG. 3 shows an example of a menu for inputting a tray speed through a drive registration information setting menu on a personal computer.

  Referring to FIG. 3, a tray loading speed setting menu 300 is shown, and the user can set a loading speed 310 and an eject speed 320 separately. Each loading speed and ejection speed can be set from slow to fast for each step. In addition, a test 330 menu is provided so that the user can test the changed and set speed, and an initialization 340 menu is also provided in which the tray speed can be set back to the initial factory shipping speed.

  In the case of an A / V set (such as a player or a recorder), a dedicated menu for setting the tray speed is provided in the A / V GUI (graphical user interface), and the tray loading speed is input through this menu. FIG. 4 shows a UI provided with a dedicated menu for speed setting in an A / V player or the like.

  Referring to FIG. 4, a tray loading speed setting menu 400 is illustrated. The user can select a loading speed 410 and an ejection speed 420 separately and set them through the setting menu 430. Each loading speed and ejection speed can be set from slow to fast for each step. In addition, a test 440 menu is provided so that the user can test the changed speed, and an initialization 450 menu is provided where the tray speed can be set back to the initial factory speed.

  The tray loading system 210 includes a tray drive motor 211, a tray controller 212, and a host interface 215.

  The tray drive motor 211 is a motor that drives the tray. The tray controller 212 controls the tray drive motor 211 to drive at a predetermined speed. The host interface 215 controls the tray controller 212 and the host 220. It mediates information transmission with the UI 221.

  First, the host interface 215 will be specifically described.

  The host interface 215 is connected to the UI and transmits a UI command to the tray controller 212 via the speed setting command 216.

  The host interface 215 can use ATAPI, SCSI, etc. Regardless of what type of host interface is used, a new vendor designation command is defined in the reserved use area and the speed setting information from the UI is transmitted to the tray controller. To do. Currently, standard host interface formats such as ATAPI, SCSI, and ATA (AT Attachment) do not define a separate command set for tray speed setting and data transmission other than tray loading / eject commands. By defining and assigning this in the spare area of the vendor-specified command area, and defining and assigning the parameter area for transmitting the speed setting value in this command, the tray moving speed setting information can be transmitted.

  In particular, the speed setting unit 213 of the tray controller 212 accepts the speed setting of the back-end unit according to the protocol agreed with the host interface 215 according to the present invention, and stores it in the setting speed storage unit 214 (nonvolatile memory). Thereafter, the tray is loaded or ejected according to the speed setting value. For example, the tray controller 212 has various step speed tables, formulas, or values (not shown) to drive the tray. The tray controller 212 stores the corresponding speed table, formula, or value in the nonvolatile memory for the speed setting value corresponding to the tray speed setting information transmitted from the host interface 215, and when the next power is turned off. It is also preferable to store this and drive the tray with this stored value.

  FIG. 5 is a flow chart showing the process of setting the tray speed according to the present invention.

  First, a tray speed change is set through the host UI (510). As described above, a tray speed setting menu can be provided through a drive registration information setting menu in the case of a personal computer, and a dedicated tray speed setting menu can be provided in the case of an A / V player. Also, the tray loading speed and the ejection speed can be set separately and can be initialized.

  The host UI receives tray speed setting information from the user and transmits the tray speed setting information to the host interface (520). Thereafter, the host interface transmits the received speed setting information to the tray controller (530). For example, the host interface can transmit speed setting information from the UI to the tray controller by defining a new vendor designation command in the reserved use area using ATAPI, SCSI, or the like.

  The tray controller stores the received speed setting information in the set speed storage unit (540). For example, the tray controller has various step speed tables, formulas, or values for driving the tray, and corresponds to a speed setting value corresponding to the tray speed setting information transmitted from the host interface. Save the speed table, formula, or value in the set speed storage.

  FIG. 6 is a flowchart showing a process of loading or ejecting a disc according to the present invention.

  If the tray controller receives a tray loading or eject command (610), the tray controller reads the tray speed stored in the set speed storage unit (620).

  The tray controller controls the tray drive motor to load or eject the tray at the tray speed read from the set speed storage unit (630).

  As described above, the tray moving speed control method as described above can be further embodied as a computer-readable code on a computer-readable recording medium. Computer-readable recording media include any type of recording device that can store data which can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy (registered trademark) disk, optical data storage device, and carrier wave (for example, transmission via the Internet). ) Are also included. The computer-readable recording medium can be distributed in a computer system connected via a network, and can store and execute a computer-readable code in a distributed manner. A functional program, code, and code segment for implementing the tray moving speed control method can be easily inferred by programmers in the industry.
